DIY! The DH-220C MOSFET Power Amplifier

[Chris]

I have a 220 I built forty years ago sitting in my garage. This may be a perfect project for 2022.

Very cool, but shame you already built it! I for one would love to follow someone's build thread on here.

audioXpress had a two part article on Hafler 220C mods in the July and August issues.  The August issue also had my article on room treatments.  Back isues are available from audioXpress.

Hey Tom, I read the article on room treatments- good stuff! I'm planning to post soon about how my own experiments have been going . I didn't catch it had an amp build in there as well. At this point, I'm already halfway there so might as well get the July one too. Thanks!

I have a DH200 that I built long ago. I built it with the Musical Concepts Super Mod kit. Was my first MOSFET power amp and have been partial to that device since. Also have the Hafler DH 101 preamp modified by Musical Concepts. They are still very good sounding pieces.

AudioXpress has a link where I believe you can get volume 1 of there 220C mod article.  Hope this works for you.
